Description

Plant-based coffee composition and preparation method and application thereof
Technical Field
The invention belongs to the field of coffee products, and particularly relates to a plant-based coffee composition, and a preparation method and application thereof.
Background
Coffee is one of three major beverages in the world, and is the main beverage popular in the world together with cocoa and tea. According to the record of Chinese herbal medicine, coffee has slightly bitter, astringent and flat taste; diuretic, stomach invigorating, listlessness and anorexia, and caffeine and theophylline which are its main active components have strong central excitation effects. The 85-250mg caffeine can enhance the working capacity of long-time mental labor and shorten the reaction time, but the working capacity related to exquisite muscle coordination and accurate timing or arithmetic is reduced; at the same time, the heart rate is slightly increased, and the systolic pressure and the diastolic pressure are increased. Although more and more researches in recent decades prove that the long-term proper drinking of coffee has a certain prevention and improvement effect on chronic metabolic diseases such as body fat, type II diabetes, tumor and the like and nervous system diseases such as Alzheimer's disease and the like, common manifestations such as insomnia, anxiety, agitation, accelerated respiration, tachycardia and the like after taking the coffee still make most people prohibitive for the coffee. Also, tannins contained in coffee promote the deposition of soluble melanoids on teeth, leaving unwanted "coffee teeth". Also, because coffee is acidic, brushing teeth immediately after drinking can weaken the enamel, resulting in staining of the teeth. In addition, the intense aroma of coffee can fade greatly with prolonged shelf life, affecting its flavor. Thus, there is a need for a natural, healthy, safe, daily drink that retains a high level of coffee flavor for a coffee preference who wishes to remain healthy or for a person who is sensitive to caffeine but who prefers coffee flavor.
Ginseng is sweet, slightly bitter and slightly warm in taste as in the Chinese pharmacopoeia; it enters spleen, lung, heart and kidney meridians. Can strengthen primordial qi, recover pulse, promote blood circulation, relieve depletion, invigorate spleen, benefit lung, promote salivation, nourish blood, tranquillize and promote intelligence, and can be used for treating body deficiency, weak limb cold pulse, spleen deficiency, anorexia, lung deficiency asthma and cough, body fluid deficiency thirst, internal heat diabetes, deficiency of qi and blood, deficiency of long-term illness, deficiency win, palpitation, insomnia, impotence and cold womb. Ginseng has been approved by the ministry of health (artificial planting) as a new food raw material in 2012 for a long time. Ginsenoside is the main active ingredient of ginseng, has the effects of exciting central nervous system and resisting fatigue similar to caffeine, and also has outstanding biological activities of soothing nerves, improving memory and learning ability, enhancing myocardial function and the like, and can compensate for caffeine 'discomfort'.
Rosa roxburghii, recorded in China Ben Cao, has sweet, sour and astringent taste; it enters spleen, kidney and stomach meridians. Has the functions of invigorating stomach, promoting digestion and relieving diarrhea. Food retention, fullness and distention, enteritis and diarrhea. From the early 90 s, the research of the rosa roxburghii which is led by a Guizhou scholars is promoted, and the rosa roxburghii contains various active ingredients such as vitamins, flavone, superoxide dismutase, polysaccharide, amino acid, organic acid, trace elements, polyphenol and the like, and has certain biological activities such as antioxidation, detoxification, bacteriostasis and the like.
Patent document CN201910466342.5 discloses a low-cause instant coffee with ginseng, but the scheme still has certain defects, such as long-time extraction of coffee beans, serious damage to the aroma and flavor of coffee, and meanwhile, the extraction process of ginseng is not guided by using effective components, so that whether the coffee can replace caffeine to play a role in refreshing is difficult to tell, and food additives such as vegetable fat powder, edible essence and the like are added into the coffee, so that the coffee has high similarity with the formula of coffee beverages on the market at present.
Based on the current situation of the current coffee beverage, the formula and the preparation process of the coffee beverage are necessary to be improved, and the plant-based coffee with the functions of refreshing brain and improving metabolic health is developed, so that common manifestations such as insomnia, anxiety, agitation, tachycardia and the like possibly caused by caffeine and the poor appearance of teeth caused by coffee stain deposition are avoided, and the current situation of serious image, product homogenization and insufficient scientific basis of functional foods and medicines on the market is broken through.
